General Motors is idling more plants and extending shutdowns at other facilities in North America due to a continued shortage of semiconductor chips that are used to control myriad operations in vehicles, including the infotainment, power steering and brake systems.

In an update Thursday, GM indicated that eight assembly plants are affected by the temporary closures. CNBC was the first to report on the temporary plant closures. GM confirmed the shutdowns to TechCrunch and added that it plans to restart production next week at its Wentzville Assembly plant in Missouri.
